These figures cover 364 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
DL 818 quarter by quarter
DL 818 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.5% on time and its weakest Jul–Sep 2026 at 70.7%, a swing of 14 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 818 did best on Wednesday at 90.4% on time and worst on Monday at 73.1%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

|---|---|---|
| 7 December 2025 | 4 hours 20 minutes | Late-arriving aircraft |

Delay causes
Why DL 818 runs late
Carrier accounts for 57% of the 4,141 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 31%Late-arriving aircraft
- 8%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,365 of the 4,141 delay minutes reported here. The split is drawn from 4,141 delay minutes reported on DL 818.
Cancellations run at 4.12%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
7.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 731 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 364 flights under DL 818 in the data flew ATL to DFW. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 364 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking DL 818
For a booking, the cancellation rate is the figure to plan around on DL 818: 4.12% of its 364 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
